Doc Bold Knight is a really good card in Steel, as youll often be getting down to 0 cards in hand: making this a cheap way of drawing to 2
Each one has a strong questing value that forces opponents to challenge or risk falling behind, and then once challenged and/or banished, their effects activate drawing you cards, forcing opponents to discard or return a character to their hand, and more
They also gained Rush, meaning they could challenge the same turn, and were banished at the end of your turn
That's next level good - it would probably be strong in literally any trading card game - but your rewards here are fleeting: at the end of your turn you put all the cards in your hand on the bottom of your deck
Its a Floodborn-type card with Shift, for one thing
